Preparation of ZnGa₂O₄ nanoflowers and their full-color luminescence properties.

ABSTRACT: Gallate material, a luminescent matrix with excellent performance is normally prepared by vapor deposition or solid phase sintering method at high temperature. However, it has not been solved to prepare gallate-based fluorescent materials with full-color luminescent properties at low temperature. In this paper, ZnGa₂O₄ undoped or doped with Cr or Mn nanoflowers composed of nanosheet-level structure were prepared by hydrothermal method at low temperature. Under ultraviolet light irradiation, ZnGa₂O₄, ZnGa₂O₄:Mn²⁺ and ZnGa₂O₄:Cr³⁺ display three primary colors of blue, green and red luminescence through self-excitation, Mn²⁺ and Cr³⁺ excitation respectively.
